Studies on Prevention of Contamination of Portable Dental Treatment Unit

在过去的几年里，在家庭牙科治疗的需求中出现了明显的增加，以至于老年人无法访问牙科办公室。更大的影响应该是为了减少这样的患者的感染风险。便携式牙科治疗单元没有抗感染设备。We attempted to use the Soft Oxidation Potential Water （SOPW） as a coolant in order to prevent the contamination of a portable dental treatment unit。这种体外研究的目标是调查便携式牙科治疗单元的控制，并估计SOPW应用的有效性。气动涡轮机手柄被操作3个周期控制，每个驱动10秒，停止5秒，在步进器突变体MT 6 R暂停（1×10 × 18 × D1CFU/ml）上。然后，手的外表面被小心地用80%的乙醇高擦拭。在10毫升的盐水中收集了一个控制性的细菌，以及一个可操作的细胞的数量被标准的分散板技术测量。没有SOPW的应用就像一个冷却器，手块被S控制。mutans MT 6 R（3.17×10字节D15字节D1CFU）。在另一只手上，当SOPW使用时，没有细菌性感染被检测到。有人建议说，SOPW有一个潜力，可以防止对便携式牙科治疗单元进行感染。

In recent years there have been a notable increase in the demand of home dental treatment due to the increasing number of elderly who cannot visit dental offices. Greater efforts should be made to reduce the risk of contamination for such patients. However, portable dental treatment units have no anti-contamination device. We attempted to use the Soft Oxidation Potential Water (SOPW) as a coolant in order to prevent the contamination of a portable dental treatment unit. The aims of this in vitro study were to investigate the contamination of portable dental treatment unit, and to estimate the efficacy of application of SOPW. The air-turbine handpiece was contaminated by operating 3 cycles, each being 10 seconds drive and 5 seconds stop, on Steptococcus mutans MT6R suspension (1×10ィイD18ィエD1CFU/ml). Then the outer surface of the handpiece was carefully wiped with 80% ethanol gauze. The contaminated bacteria in the handpiece were collected in 10 ml of saline, and the number of viable cells was measured by a standard spred-plate technique. Without application of SOPW as a coolant, the handpiece was contaminated with S. mutans MT6R (3.17×10ィイD15ィエD1CFU). On the other hand, no bacterial contamination in the handpiece was detected when SOPW was used. It was suggested that SOPW had a potential to prevent contamination of portable dental treatment units.
